I may sound cynical, but I wonder if pharma companies would ever be interested in search for a cure for a malignancy or other deadly disease. Wouldn’t it be harming their own interests?
Why would a profit-driven company turn away curing the second leading cause of death? It's a market whose yearly demand is going to be in the tens to hundreds of thousands in the US alone, even if you're only going to be on the drug for a short amount of time.
